Title (EN) METHOD AND ADJUSTING DEVICE MECHANISM IN CONJUNCTION WITH AN ALUMINIUM SMELTER
(FR) PROCÉDÉ ET MÉCANISME POUR DISPOSITIF D'AJUSTEMENT, ASSOCIÉ À UN FONDEUR D'ALUMINIUM
Abstract: front page image
(EN)The invention relates to a method for operating an anode adjusting device mechanism of an aluminium smelter and to a corresponding adjusting device mechanism. In the method, an aluminium production cell being used comprises a cathode forming a base of the production tank, and an anode held at a suitable distance above the cathode by lifting and lowering the anode. According to the invention, some rotating part of the adjusting device mechanism is braked when the anode is being lowered down and the bearing (9, 10) of the rotating part, such as a toothed shaft (4), allows movement of the shaft in the axial direction such that the axial force generated by the toothing presses a friction surface of a brake structure coupled to the rotating part in the anode lowering direction, braking the rotating movement. The adjusting mechanism comprising a lifting screw (3) carrying the anode, a worm gear (2) supporting the lifting screw, and a worm shaft (4) rotating the worm gear (2) and coupled with a power device for its rotation in both directions, the adjusting device mechanism comprises a brake mechanism (13) coupled to the worm shaft (4) for braking the worm shaft when the anode is being lowered, and that the worm shaft (4) is fitted with a bearing so as to rotate as well as to move in its axial direction to a small amount, the brake mechanism (13) comprising a brake element (11) supported to the worm shaft (4), and a friction material (12) at a distance from it when the anode is being lifted and engaged to the brake element due to said axial movement when the anode is being lowered.
(FR)L'invention concerne un procédé de fonctionnement d'un mécanisme pour dispositif d'ajustement d'anode, d'un fondeur d'aluminium, et un mécanisme correspondant pour dispositif d'ajustement. Dans le procédé, une cellule de production d'aluminium utilisée comprend une cathode formant une base du réservoir de production, et une anode maintenue à une distance convenable au-dessus de la cathode par soulèvement ou abaissement de l'anode. Selon l'invention, une partie rotative quelconque du mécanisme pour dispositif d'ajustement est freinée lorsque l'anode est abaissée.
